VENTILATING SYSTEM FOR BAILWAY-CARRIAGES AND THE LIKE no. 900,614.Original application at March '1, 1905, stun following is aspecification, reference being had to the drawings hereunto annexed andto the figures and reference-numerals marked thereonthat is to say Theinvention relates to a ventilating sys tem for railway carriages and thelike'and is a divisional application from applicant's coendinapplication Serial No. 248,802, filed ar. 7t I905.

Accordin to the present invention fresh outer air w 'ch has assedthrough filtering devices is introduced near the roof thereof and thefoul or 'vitiated air is extracted from the carriage through outletsalso arranged in or near the said roof.

In the accompanying .drawings:-Figures 1 and 2 are respectively alongitudinal and a transverse section, the sections being taken on thelines A A and B-B of Fi s. 2 and 1 respectively of a railway. carriageustrating the application thereto of the present invention and Figs. 3and 4 are respectively similar views to Figs. 1 and 2.i llustrating aslight modification.

Referring to the drawings 1 is a receiver or collector into which freshair from the outside of the railway carriage is forced by the resistanceoffered by the more or less quiescent air to the motion of the carriageand forated ends 2 and perforate said receiver consists of a casinhaving pertering partitions 3 and it is provided with a light swingingvalve-4' pivotally mounted by its upper edge and which according to thedirection of motion of the carriage assumes an 'angul flects the currentof air downward into the bod of the receiver.

any suitab 'air filter 5 and the deflected current of alr'is T e body ofthe receiver 1 is provided with e filtering Tmedium constituting an comelled to pass through said filter as shown by t e arrows in Figs. 1 and3 and which has the effect of arresting any particles of soot, coal andthe like, carried 1n the air.

The body of the receiver 1 communicates with a passage or conduitextending over Specification of Letters Patent.

the entire length of the carriage exteriorly or it might be interiorlythereof as shown at Flgs. 3 and 4 and the current of filtered aircarriage.

Hand regulating valves 11 are rovided between the conduit 6 and thereceiver 1 to control the volume of atmospheric air ass ing to theinterior ofthe carriage. ile fresh filtered air is thus introduced intothe carriage, the foul air is sucked out therefrom through outlets 10provided in the roof of the culiar ventilation efi'ect described in myap- R lication hereinbefore referred to is insured.

he outlets1 10 may be so constructed in any well known manner that. byreason of the rapidpassage a suction like action is roduced and theremoval of the foul air t us effected or if desired other well knownmeans mi ht be rovided for extracting the foul air;

' t will e understood that the constructive details hereinbefore shownand described are merel given by way of..example and are capab e ofvariation without departing-from the spirit of the invention.

By, he means hereinbefore described the foul or' vitiated air is removedfrom a railduced 'thereinto without to any great extent mixing with theformer while at the same time the incoming air is more or less heated bypassing in close proximit to the outgoing warm but foul an and t us theatmoswholesome condition from a hygienic standpoint and by reason of theeculiar relative positions of the inlets an I outlets this is achievedwithout creating an appreciable draft.

Having now particularly described and ascertained the nature of t e saidinvention formed I declare that what I claim is:- I

1. In a ventilatin system for railway carriages and the like t ecombination of a conduit extending longitudinally along the roof vfreshair is distributed'in the interior of the' carriage or adjacent thereto,so that the peway carriage or the like andfresh air is intro-- phere ofthe carriage is maintained in a.

and in what manner the same isto be perpasses into said conduit. Pipesor tubular -'of the carriage, conduits extending trans- 'ways connectingthe longitudinal conduit vcrsely of the roof of the carriage, tubularwith the transverse conduits, said conduits being open on the undersideand there covered with filtering material, an air receiver on theexterior of the carriage conimunicating with the longitudinal conduitand provided with an air filter, a swinging valve in the receiver fordeflecting the alr current toward the filter in either direction ofmotion of the carriage and air exhaust ways extending through the roofof the carriage as set forth.

2. In a ventilatin system for railway carriages and the like thecombination of a conduit extending longitudinally along the roof of thecarriage exteriorly thereof conduits 1 extending transversely of theroof of the carriage interiorly thereof, tubular ways connecting thelongitudinal conduit with the transverse conduits, said conduits beingopen on the underside and there covered with filtering material, an airreceiver upon the exterior of the carriage communicatin with thelongitudinal conduit and provide with an air filter a swinging valve inthe receiver for deflecting the air current toward the filter in eitherdirection of motion of the carriage and air exhaust wa s extendingthrough the sides immediate y below the roof of the carriage as setfortl SERGIUS TIMOCHOWITSCH.
